How to prime Graco MAGNUM PROJECT PAINTER PLUS Paint Sprayer?
- SSandra RoachAug 17, 2025
To prime your Graco Paint Sprayer, first, ensure the Prime/Spray Valve is in the PRIME position. Check that the inlet screen is free from clogs and the suction tube is fully immersed in the fluid. If these steps don't work, remove the suction tube from the paint and prime the pump using water or a solvent-based flushing fluid. If the inlet valve check ball is stuck, remove the suction tube and use a pencil to dislodge it, or try Power Flushing the sprayer. Also, check for and tighten any leaks in the suction tube connection. If the fluids you're using are viscous, try momentarily turning the Power Switch off and on to slow the pump.
